MedicineWorld.Org: Lung cancer main page

There are two
basic types of lung cancer. Small cell lung cancer (previously known as
oat cell lung cancer) comprises of about 20% of all cases of lung
cancer. All other lung cancer types are collectively called non-small
cell lung cancer. Non-small cell lung cancer consists of a heterogeneous
group of lung cancer with mainly three sub types: adeno carcinoma,
squamous cell carcinoma, and large cell carcinoma. Even though the
non-small cell comprises of different cell types, they usually show a
similar behavior and are mostly treated in a similar way. Following is a
break up of sub-types of non-small cell lung cancer. Adenocarcinoma (40%
of all lung cancers), squamous cell type (30% of all lung cancers),
large cell type (10% of all lung cancers).
